Radiometric dating methods are used to establish the geological time scale.

Elements exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.

Radiometric dating (often called radioactive dating) is a way to find out how old something is.

The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. It is the main way to learn the age of rocks and other geological features, including the age of the Earth itself.

Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.
